Many of us try to change bad habits quickly, and if we are not successful straight 8.  away  , we often become pessimistic and give up. In fact, the most successful way to change is not suddenly, but over a period of time. To reach the goal of change, a person must 9.  repeatedly  (repeat) take many small steps. Young people have the power 10.  to build  (build) a happy and healthy life full of good habits!

三、it作形式主语的句型
1.It is/was+形容词+(for/of sb)+动词不定式
(1)It is/was+形容词+(for sb)+动词不定式

It is necessary for us to master some basic living skills.
我们有必要掌握一些基本的生活技能。
(2)It is/was+形容词+(of sb)+动词不定式
表示心理品质或性格特征的形容词(如kind、 nice、 stupid、clever、foolish、 polite、impolite、 silly、selfish、 considerate等)常用于此句型,动作的逻辑主语与这些形容词可以构成主系表结构,因此这样的句式也可转化为“sb+be+形容词+动词不定式”。

→You are foolish to trust a person like him.
